IN VENTOR vmr@ ATTORNEYS United States Patent SCOOP WHEEL Egon Frick, Bad Schwartau-Cleverbruck, Germany, assignor to Orenstein-Koppel und Lubecker Maschinenbau Aktiengesellschaft, Lubeck, Germany Application May 4, 1956, Serial No. 582,811 1 Claim. (Cl. 37-189) This invention relates to scoop wheels for excavating machines or other material handling apparatus.

In the co-pending application of Rasper et al. Serial No. 507,659 filed May 11, 1955 for Scoop Wheel, an apparatus is disclosed in which the material picked up by the scoops on the periphery of the wheel is dropped upon a rotating disk which transfers the material to a conveyor.

The object of the present invention is to improve upon the discharge disk so that the material dumped thereon is less impeded in its transfer to a conveyor.

In general, the object of the invention is obtained by arranging the disk having a radius greater than the width of the scoops so that it extends beyond either side edge of the scoops. Material dumped from the scoops drops directly on the disk without any lateral deflection thereof being necessary. This enables the elimination of chutes between the scoops and the disk. It is desirable to have substantially perpendicular bafiies mounted beneath the edge of the scoops above the outer peripheral portion of the disks, in order to prevent material from bouncing 011 the disk. These baflies, in turn, are connected to shields for retaining the material on the disk until the disk rotates the material to a discharge position on the conveyor.

In order to provide room for the extent of the disk beneath the scoops, the spokes of the scoop Wheel are angularly mounted.

The means by which the object of the invention is obtained is described more fully with reference to the accompanying diagrammatic cross-sectional view of a scoop wheel:

The scoop wheel is composed of an axle having spokes mounted thereon. Each spoke has inclined outwardly directed portion 12 fastened to axle 10 and continued into vertically inclined portion 14 connected to and supporting the rim consisting of cross beam 16 and rign-like members 18 to which the scoops 20 are fastened. A gear box 22 connected to axle 10 supports a vertical outwardly inclined shaft 24 upon which discharge disk 26 is rotatably mounted. Gear box 22 is such that the disk is rotated at a greater velocity than the scoop Wheel.

Disk 26 has a diameter greater than the distance between the planes of rings 18 so that the disk extends clear across and beyond the width of scoops 20. Clearance for this extent of the disk is afiorded by reason of the elbow 28 between the portions 12 and 14 of the spokes.

Adjacent the outer edge of disk 26 and approximately perpendicularly beneath rings 18 is a battle 30 whose function is to prevent the material dropping from the scoops 20 to disk 26 from bouncing off the disk. In turn, this baffle is joined to a shield 32 extending transversely of the scoop wheel and continued into a guide wall 34 extending to the conveyor belt 36, mounted above axle 10. Thus, material is retained on the disk until it reaches the discharge position above conveyor 36.

In order to facilitate the transfer of the material, a conical hubcap 38 is placed over shaft 24.

Having now described the means by which the object of the invention is obtained,

I claim:

In a scoop wheel having an axle, spokes secured to the axle, a rim frame mounted on said spokes, scoops carried by said rim frame, and a discharge disk supported by and rotatable by said axle beneath said scoops, the improvement comprising said discharge disk having a radius greater than the width of said scoops mounted so that said disk extends beyond the side edges of said scoops, and said spokes each comprising an outwardly inclined portion fastened to said axle continued into an inwardly inclined portion secured to said rim frame to form an elbow providing clearance for said disk.
